Yes, the MMA world is reeling from reports today that dos Anjos recently broke his foot while training, and as a result, he will not fight McGregor on March 5th. Combate has reported the injury, and MMA Fighting is also reporting RDA will not fight at UFC 196.
According to the latter report, the UFC is looking for a short notice opponent for McGregor. The promotion hasn’t made any announcement regarding the situation.
So, obviously this is awful news. The UFC might be able to put together an interesting replacement bout here, but it won’t be lightweight champ vs. featherweight champ.
